help$2.($a$)$ A Statistical Time Division Multiplexing $($TDM$)$ is as shown in Figure $3.$

$($i$)$ Suggest and sketch the frame structure of the TDM output if $1$ overhead bit is added

to each frame using $2$ bits per slot. How many bits in a frame?

$($ii$)$ Draw the TDM output stream.

$($iii$)$ Determine the bit rate of the TDM link and the time delay between the first bits of

the same numbered slot in successive frames.
